A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank:G4

A Global Rarity Rank of G4 means: Apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery.

There are over 1,000 species of Clubtail dragonflies known worldwide (Nikula et al. 2003). This mostly black species of Clubtail is aptly named, as its common name, Sable Clubtail, means black with a clubbed tail.

The Sable Clubtail is known from two locations in Orange County, New York, with population estimates undetermined. Further survey efforts may result in the identification of additional populations or range expansions, and may enable population size estimations.

No estimate of population size for the Sable Clubtail has been made between the late 1980s to 2000 (New York Natural Heritage Program 2007). Information prior to this time frame is even more limited. Therefore, any new location information on the Sable Clubtail in New York may reflect heightened interest in surveying for this species rather than a population increase or a range expansion (Holst 2005).

Recent observations of Sable Clubtails were made between the late 1980s to 2000 in Orange county, (Donnelly 2004, New York Natural Heritage Program 2007). Since these are fairly recent records, and the full extent and size of the populations have not been determined, long-term trends are unclear.
